    +1 on this.
  2. Re: Use of X-ray film: technical discussion with example images

    Was this from the manufacturer? A supplier? Or somewhere else?
  3. Re: Use of X-ray film: technical discussion with example images

    Mohmad, there are so many variables that our past experience may not apply to your exact situation with this film. Just as with regular film, it's best for you to do your own exposure tests and...
  4. Re: Use of X-ray film: technical discussion with example images

    Your link is malformed; it should start with "http://" but it starts with "ttp://". In any case, I was able to look at the datasheet & it doesn't provide a lot of useful information. The film is...
  5. Re: Use of X-ray film: technical discussion with example images

    I did not know about the latter type. You would probably get decent results with it after some trial-and-error.
  6. Re: Use of X-ray film: technical discussion with example images

    The developers used by hospitals are intended for use in their rapid development machines. I don't think you'd get the same result by, say, tray developing or developing in a daylight tank meant for...

    Re: Collodion - Wet Plate Images

    There used to be an article by Alex Timmerman on the internets somewhere in which he demonstrated that the exaggerated swirl you sometimes see in images made with a Petzval is the result of an...

    Only Ektascan & other single-emulsion x-ray films have anti-halation backing. And they are all on blue polyester substrates.

    The emulsion is much softer when it is wet, hence easier to scratch. But you can scratch it when it's dry too.

    Server error for x-ray thread only.

    +1 for this cutter. Often listed used on fleaBay for a substantial discount.

    Re: Trial with the new B's 4x5 Developing reel

    I've actually ordered parts from Omega Brandess thanks to an earlier post by you, Bob. Good to know they have plenty of parts remaining.

    Re: Trial with the new B's 4x5 Developing reel

    That's why I fill and drain mine with the lid off and in the dark (or under red light for x-ray film). The real barrier is it's no longer being manufactured & the remaining stock of spare parts is...

  23. Re: Use of X-ray film: technical discussion with example images

    Apart from the pollution, I think you are farther north. Beijing = lat. 39.9042° N; OKC metro = 35.4676° N. So I'd probably need a slightly shorter exposure.

    Window light? What time of day?
  25. Re: Use of X-ray film: technical discussion with example images

    Please order one or two of these. Use them with a reflector-type shop light pointed away from your work area (bounce the light off the ceiling). If you use two bulbs together you'll want this adapter.

  28. Re: Lightweight Tripod for Large Format Recommendations

    One of the nice things about the Gitzo 1542 (and others in the series) is they have a hook on the bottom of the center column. Carry an empty sandbag, fill it with rocks or dirt, and hang it from the...

    Fantastic!
  31. Re: Use of X-ray film: technical discussion with example images

    I have to agree that single-sided is sharper. I've used both & it's pretty clear from my results.
  32. Re: Use of X-ray film: technical discussion with example images

    I've used TF-4 and Kodafix. Plan to use TF-5 when I run out of TF-4. Supposedly acid-based fixers (Kodafix) can bleach staining developers, e.g., Pyro, but since you're using Rodinal it won't matter.
  33. Re: Use of X-ray film: technical discussion with example images

    No sweat. It's cheap and it's a great way to learn. The main things is to handle it carefully. Your cutting area needs to be very clean; lay down an old, but laundered, cotton sheet under your...
  34. Re: Use of X-ray film: technical discussion with example images

    The x-ray film I've used has rounded corners. Since I cut each sheet into 4 negatives there's always a rounded corner that acts as the film notch for me. Always place it the same way and Bob's your...
  35. Re: Use of X-ray film: technical discussion with example images

    In a clinical setting, the x-rays pass thru the film and excite pixels on a phosphorescent screen (an "intensifier screen"). The phosphors emit visible light of a wavelength that matches the...

    Same here, depends on total price.

    Never mind, just saw it's UK only.

    Re: Collodion - Wet Plate Images

    Excellent! Good demonstration of how collodion sees, or rather doesn't see, red.

    That's where covering some cardboard with aluminum / aluminium foil to use as a reflector on the shadow side comes in. ;-b
  40. Re: Use of X-ray film: technical discussion with example images

    Nice. Have you considered putting a reflector or a fill light on the shadow side?
